HEATING ATTACHMENT FOR GAS-BURNERS.

SPEGIFIGATION forming part of Letters Patent N o. 7 32,085, dated June 30, 1903. Application filed August 11, 1902. Serial No. 119,318. (No model.)

To atZZ whom, it may concern;

Be it known that I,WILLIAM A. KoNEMAN,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Heating Attachments for Gas-Burners, of which the following is a specification.

My invention relates to an improvement in portable gas-burning heating devices, for use more especially as room-heating attachments for illuminating-gas burners.

My object is to provide certain improvements in the construction of such a device, primarily to increase its efficlency and desirability as a heater, and also to adapt it for ed for use with the device; Fig. 6,a broken and enlarged section taken on line 6 in Fig. 1,showing the vessel-supporting stand in place; and

Fig.7, a section on line 7 of Fig. 1, where the device is shown suspended from the gas-fixture.

Ais the device, having as its main constituent parts a top plate B, a burner-plate C, a partition D, a flaring tube or cylinder E, a central tube F, an air-baffle plate G, a gasbafie plate H, a strainer I, and a plug F, all constructed, preferably,- as shown. The plate portions described may all be of thin sheet metal. In the top of the tube F is an internal screw-thread a, in which fits a removable screw-plug b. The top plate B is bent to present an annular groove 0. and D are fastened together at their outer edges, and this fastening may be effected by flanging one over the other, asshown, by brazing the plates together, or in any other desirable way. At the centers the plates or disks B D are fastened by brazing or otherwise to the tube F, while the cup-shaped disk 0 is fastened at its center around the tube or cylinder E. The partition-plate D is preferably provided with annular corrugader or tube E is fastened at its around the tube F and partly supports and being indicated by dotted arrows. between the flaring end portion of the airtube E and the partition D forms an initial The plates B, O,

tions, as shown. The part 0 is provided with an annular series of narrow elongated slits or burner-openings cl, preferably extending more or less spirally, as shown. The cylinlower end is partly supported by the plate 0. The baffle-plate G is a curved disk fastened-around the tube F, and the disk His flat and also fastened around the tube F. The strainer I fits around the edges of the baflles G H and contacts at its upper and lower ends, respectively, with the partition D and flaring upper end portion of the tube or cylinder E. The plug F forms a gas-tight diaphragm in the tube Eat the batlie H. In .the tube F above the plug are series of perforations e, and below the said plug are series of perforationsf. In the lower end of the tube or cylinder Eis a series of air-inlet openings 9.

The device may be connected with a gassupply either at the upper or the lower end of the tube F, both said ends presenting gas-supply attaching-openings. In Fig. 7 the device is shown suspended with relation to its support, which support may be an illuminating gas burner of any kind, a chandelier, as shown in Fig. 1, or any gas-supply connection. When the gas is turned on, it enters the tube F at the top of the latter, its course being indicated by the full-line arrows. Air to'miX with the gas enters through openings g and also the lower end ofthe tube, itscourse Thespace air and gas mixing chamber h, terminating in a comparatively narrow annular outlet h.

The burner-plate O surrounds a larger annular mixing-chamber 1', having the burner-outlets d. The gas entering the tube Fescapes through the perforations e above the batheplate H and through the screen I to the'initial mixing-chamber h, into which air is drawn through the openings g and f. Initial mixing takes place in the chamber 72, andthe mixed gas and air passes into the chamber '5 and escapes under comparatively little pressure at the burner slits or openings cl, where it is ignited. The gas mixture burns over a comparatively large area of the surface of the burnor-plate O, producing a blue flame of high intensity, which heats the plate to a high temperature, so that the radiation of heat therefrom will raise the temperature of the surrounding atmosphere very rapidly. By reason of the fact that the flame heats a metallic surface from which the heat is radiated in the downward direction the best results are obtained in heating a room by having the device more or less near the floor of the room. Thus a desirable way of employing thedevice is to suspend it from a droplight tube L, as shown in Figs. 1 and 7. The tube L is provided toward its lower end with a valve Z, the connection between the tube and valve being through a wooden or other non-heat-conducting sleeve-piece Z, suitably fastened between the tube L and valve or fitting l to prevent the rubber of the tube from being injuriously affected by heat from the heating device. The lower end of the fitting Zscrews into the threaded attaching-opening a, and the tube L thus holds the device in suspended relation to the chandelier or other support. This construction permits the heating device to hang suspended more or less near the floor of a room, while receivingits gas from above.

The device, as shown, is also adapted to fit at the lower end of its tube F over the illuminating-gas burner on a chandelier or gasfixture of any kind. When the device is to be used solelyin this way for heating a room, the plug b should be in place, as shown in Fig. 4. When the gas is turned on, it enters the lower end ofthe tube F, its course being indicated by the full-line arrows. Air to mix with the gas enters only through the openings g, as indicated by the dotted arrows. The gas passes through the openings f above the baffle-plate G and the air enters beneath the bafifle-plate G, both passing to the initial mixing-chamberh,tl1ence to the mixing-chamber i, and out through the burner-openings d.

If desired, the device may also be employed for heating a small vessel of water. When it is to be used for this purpose, the plugb is removed and a removable burner-cap 70 (shown in Fig. 6) is placed upon the device to present a small orifice for the escape of a portion of the gas mixture. K is a removable stand having legs fitting into the groove 0 at the top of the device and presenting a support for a cup or other vessel in which water is to be heated.

If desired, the space or chamber m between the platesB D may be filled with asbestos fiber, mineral wool, or other insulating material to maintain the plate D comparatively cool, so that it may be handled by the ringed plug b without danger of burning the fingers.

Constructed as described my improved heating device is not only efficient as a heater, but is ornamental and economical in the use of gas.

While I prefer to construct the device throughout as shown and described, it may be variously modified in the matter of details of construction without departing from the spirit of my invention as defined by the claims.
